A novel human UDP-N-acetyl-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase, GalNAc-T7, with specificity for partial GalNAc-glycosylated acceptor substrates.

abstract：:Spermidine N1-acetyltransferase in an extract from phytohemagglutinin-stimulated bovine lymphocytes was inactivated by preincubation with alkaline phosphatase. Inactivation of the acetylase with the phosphatase was totally inhibited by addition of pyrophosphate. These results suggest that spermidine N1-acetyltransfera...
